Subject: CVNET: request for colorimeter info.
Dear CVNETers,
I am looking for a comercially available visual colorimeter.
One one side, it should have 3 knobs for adjusting the amounts of
three primaries, to make a visual match. The knobs should be calibrated;
relative units are enough.
One the other side, it should have a location to
place a sample, to be illuminated by white light.
I do NOT want any electronics, because this is for teaching,
so the students should be able to see what they are doing.
I do NOT want a Singerman apparatus, because although this shows
mixtures of 3 primaries, it has no place for a sample or test stimulus,
and it is entirely uncalibrated.
I thought 'tintometer' would have the right euipment, but after 100 years
they now only make electronic colorimeters.
If anyone has any suggestions, I'll be deeply grateful. I don't
look forward to having to make a bunch of lab set-ups by hand.
